Networking :: Pipe_server Running At Port 2010?
Nov 10, 2010
I don't find a lot of information available regarding a service called pipe_server.When I send UDP packets without specifically a source or destination port, the packet capture from the machine, I send the UDP packet shows the following:
src port: pipe_server(2010)
dest port: pipe_server(2010)
More information related how send packets : I use raw sockets. I don't specify ports.Does the kernel fill the src and dest ports for me? Do all machines have a port 2010 that will listen for UDP packets?

I am getting a problem to run hugin 2010.2.0 in Slackware 13.1. After I installed all require programs (I hope that), I run hugin, but the error message show that:
bash-4.1# hugin Fatal Error: Mismatch between the program and library build versions detected. The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with 2.6),
and your program used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with 2.4,compatible with 2.6)." Is there anyone know how to fix this problem?

have very limited experience with command line interfaces in Mac OSX (the OS that I'm used to). Please pitch any replies at the appropriate level My problem:I've installed Mandriva Spring 2010 Free in a Parallels Desktop 5 VM running inside Mac OS X 10.6 (Snow Leopard).Parallels has a set of tools that I need to install to make the VM play nicely with my host OS. It is here that I'm running into problems. When trying to install Parallels Tools I get a warning that 'Some components needed for parallels tools installation are missing in your system;. I'm offered the chance to download them automatically. This download always fails and I'm told that I need to download 'kernel sources' manually and try again.
After some considerable research (remember I'm TOTALLY new to Linux) I found out what this means and have installed what I believe are the correct files using the 'install and remove software' window. As I understand it, I need to download the source files of the kernel I am using (exactly the same version), so I now have:kernel-desktop-latest - Version 2.6.33.5ernel-source-latest - Version 2.6.33.5These are 'virtual rpm's that make sure i always have the latest kernel versions, which as I understand it means that I should have the latest kernel and corresponding kernels sources... but I still get the damn error message telling me to install 'kernel sources' when I try to run the parallels tools installer.

I have a simple server running Ubuntu Server. Usually the server connects to the network by Wifi, so there is usually no cable connected to the Ethernet port. I noticed that there is a dhclient3 running on eth0 anyway. It is causing undesirable disk activity. Obviously, it is never going to get a response as long as no cable is connected. I can kill the responsible process manually, but I wonder first what is starting the process and how I can prevent it from being started. If there is a way to get the server to boot without starting this process, I wonder whether this is the right solution. Connecting to the network by Ethernet is the failsafe when Wifi doesn't work. I guess what I would like to see would be a way for the server to detect when eth0 does not have a cable connected and not start dhclient in that case, but to activate dhclient when a cable is connected.

My first time installing centos server and adding it to xp home network. I am new to setting up my own network in general. I have a home windows wired ethernet xp network (simple linxs router) with 2 xp boxes and one centos5 box all connected to the same router. I just set up the centos box running tomcat on port 8080. I need to do two very basic things at this point, but am not sure what I need to do:
What do I need to do so I can:
1. Connect in firefox on one of my xp boxes and call the tomcat server running on my centos box?
2. Be able to ftp to centos box from either of my xp boxes?

I have been using PCLOS for a few years now, 2007 and 2009. My PC connects via eth0 to an ADSL modem/router either with static IP or DHCP and Internet works fine.
I formatted a partition and installed PCLOS 2010.7 KDE to it. I booted the new system, expecting to (almost) never see the old one again. But I was surprised to discover that I cannot access anything on the Internet.
In the taskbar I see the network icon which correctly shows my IP and the default gateway (my router) and DNS address. When I open Firefox and fill in a location I get "waiting for [URL]" (or whatever site) forever! I couldn't even get a response from the router itself, on my own local IP segment!
As soon as I rebooted my PCLOS2009 I was online again as usual, so the hardware and network defs sure seem OK.
On the basis of a suggestion I checked my FireFox settings, and found that I had network.dns.disableIPv6 setting as 'false' in Firefox, and I changed it to 'true'. I also changed the proxy setting from 'system proxy settings' to 'no proxy'. These changes did not help, I still cannot connect.
in no particular order:
1) from a shell I can ping any site, by IP *or* by dns name.
2) my browser gets NO response from my router at 10.0.30.100 but if i type the url ftp://10.0.30.100 I *DO* get a prompt for my password from the router. (After I give the password it tells me that ftp is not available, which is true).
3) I have found *ONE* web site that worked in my browser: [URL]
4) Another app that also failed to connect to the Internet: Synaptic does not download repository listings. So I have not tried any other browser, since I cannot install anything.
5) I checked my firewall settings (in the control center) and it says that I have NO firewall limitations.

Bit of an odd one this. My ZTE MF100 (on O2) had been working happily on my 10.04 laptop, but today is not recognised - e.g. no device listed by lsusb, nor error messages in dmesg at boot.
Re-plugging the device after boot gives me dmesg errors:
[ 1691.680162] usb 5-2: new full speed USB device using uhci_hcd and address 9
[ 1691.810163] usb 5-2: device descriptor read/64, error -71
[ 1691.990379] hub 5-0:1.0: unable to enumerate USB device on port 2
[Code]....
I can't see any suspicious entries in /var/log/dpkg, but I'm attaching a copy of the recent anyway, along with output for lsusb -vv.

When I use the following command:
ssh user@ssh_server -L 5500:localhost:5500 -p 22
everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:
ssh user@ssh_server -R 5500:localhost:5500 -p 22
I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...

I'm trying to use iptables in order to forward all the incoming packets for port 5555 to port 5556 on the same server (192.168.2.101).
I wrote the following commands:
iptables -A PREROUTING -t nat -i any -p tcp --dport 5555 -j DNAT --to 192.168.2.101:5556
iptables -A FORWARD -p tcp -m state --state NEW -d 192.168.2.101 --dport 5556 -j ACCEPT

I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
iptables -t nat -A PREROUTING -p tcp -i eth1 -d (WANIP) --dport 21 -j DNAT --to 192.168.1.2:21
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..
Here i my iptables script:
#flush table
iptables -F
#input regler

I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452
Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!

I had to add them to my firewall script when I installed openvpn on my dd-wrt router:
iptables -I FORWARD -i br0 -o tun0 -j ACCEPT
iptables -I FORWARD -i tun0 -o br0 -j ACCEPT
iptables -I INPUT -i tun0 -j REJECT
iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE
what should I add/change to set up port forwarding of port 1000 to ip 192.168.1.200. also how to get the answer sent by 192.168.1.200 follow the same route used by the data received through port forwarding.

i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.

I have two computers on a LAN. (This is history not a Bazaar question, although I have one of those too) One of them (Ubuntu 9.04) Im using as a Bazaar repository over sftp. Its been working fine for about a year. Then we had a thunderstorm that knocked out our Internet service for a couple of days. When it came back up everything is working fine accept I could no longer commit to the server. A little detective work showed that ssh was not running on the server. I started it and Bazaar then couldnt find the repository files. I still suspected an ssh problem, but port scans from both computers showed port 22 open on the server and I could do a ssh login from the client ok. Then I started fiddling with ssh on the server and now I have ssh problems on top of the Bazaar problems.
On the server I deleted then regenerated the ssh keys. Ive done
sudo /etc/init.d/ssh reload
sudo /etc/init.d/ssh start
I get a normal starting message and ps ef |grep ssh
shows /usr/sbin/sshd running. But the port scan does not show 22 open and I get connection refused at the client.

I searched a bit on the 'snet-sensor-mgmt' but I couldn't make sense of what it is for. Why is it running? and does it have to be on port 10000? I am thinking of installing webmin, but that port is taken. Fedora 14.

I don't think it would be harmful to run ssh on the default port of 22. Especially since the machine will only accept key-based logins and only accept traffic on port 22 from external IP addresses that I specify.

I'm running both Apache on my site and Etherpad Lite, both on different domains. However, running them both on port 80 causes a conflict. I tried to use a reverse proxy in Apache (this is the configuration -- I'm not sure if I did it right), but it doesn't seem to do anything.

I have a crontab on my vps running every minute that checks to see whether or not a certain port is open on localhost. If the port isn't open, it should run the php script to restart the program. However, I require the use of screen to be able to interact with the program whenever I reconnect to the vps through shell.The problem is, screen is being a pain by saying "Must be connected to a terminal."This is the php script:
